想要去了解python中的property函数
搜:
python property函数
参考:
看到示例如下:
class Student(object):@property
def score(self):
return self._score
@score.setter
def score(self, value):
if not isinstance(value, int):
raise ValueError('score must be an integer!')
if value < 0 or value > 100:
raise ValueError('score must between 0 ~ 100!')
self._score = value对应的输出:
>>> s = Student() >>> s.score = 60 # OK,实际转化为s.set_score(60) >>> s.score # OK,实际转化为s.get_score() 60 >>> s.score = 9999 Traceback (most recent call last): ... ValueError: score must between 0 ~ 100!
